Definitions
- the present invention relates to a fire alarm.
- Fire alarms are used for the early detection of fire in fire-prone areas, to protect individuals and assets.
- Fire alarms are typically installed on ceilings and have a round, white housing with a diameter of approximately 10 cm and a height of approximately 7 cm to 10 cm. Due to its function, the housing rests against the ceiling.
- Fire alarms are industrial, series-production products, and fire alarms of the same type and that are made by the same manufacturer typically look the same.
- the fire alarm on the ceiling is typically recognized immediately as a fire alarm due to the size of its housing. The uniformity of series production and the housing shape are therefore always a compromise between the function of the fire alarm and the user's taste, and the aesthetics of the surroundings.
- a light-scattering smoke detector is made known in DE 101 18 913 A1, which includes a light transmitter and a light receiver arranged such that a scattering point is located outside of the light-scattering smoke detector, in an open space, the light-scattering smoke detector including a cover for protecting the light transmitter and the light receiver, and means for distinguishing between smoke and other foreign objects located in a region around the scattering point.
- the means for distinguishing between smoke and other foreign objects includes a processor for analyzing the time profile of reception signals from the light receiver, it being possible to connect the processor to the light receiver.
- the technique applied by this light-scattering smoke detector for detecting fire makes it possible to install the light-scattering smoke detector essentially flush with the ceiling.
- a fire alarm with a color that matched upon installation would then be perceived again as a distracting foreign object.
- the fire alarm cannot be subsequently painted to match the new surroundings, since, in the case of a fire alarm mounted flush against the ceiling without an optical labyrinth, there is a risk that painting it in a careless manner could negatively affect the responsiveness of the fire alarm.
- Publication DE 101 18 913 A1 also makes known a light-scattering smoke detector which includes two light receivers or focusing optics for a light receiver for adjusting a defined measurement volume.
- the fire alarm designed according to the present invention offers the advantage of universal usability, since it can be adapted to practically any type of surroundings in a simple, cost-effective manner.
- the fire alarm has a covering cap which is connectable with the housing of the fire alarm and closes the housing such that it is flush with the ceiling.
- the covering cap has a recess into which pre-stamped sheets can be inserted before the covering cap is placed on the housing of the fire alarm. Sheets of this type can be manufactured economically, in a large variety of color-fast shades.
- the covering cap is preferably designed to be transparent.
- the fire alarm is preferably designed, as a series-production product, as an installation set that includes sheets in colors typically found in living spaces.
- the housing and covering cap are preferably connectable with each other via a detent or clip connection.
- a Velcro closure can also be provided.
- Detachable connecting means of this type provide a secure hold for the covering cap on the housing of the fire alarm. They also make it possible for the covering cap to be easily removed for replacement of a sheet and to be reconnected with the housing.
- the material and shape of the covering cap can help facilitate the color match. For example, a slightly convex shape of the covering cap can enhance the impression that shades of color transition in a visually-pleasing manner.
- the covering cap can also have a slight mat finish on all or at least part of its surface to further enhance this impression.
- the covering cap and/or faceplate can also be designed as templates to be used to cut covering material to fit.
- covering material that matches the surroundings can be cut to fit at the installation site and inserted in the covering cap instead of a sheet.
- a sheet with a contrast color that deviates significantly from the surroundings can also be used, of course, if this is desired for interior-design reasons. Special optical effects can be attained as a result. This high degree of flexibility is made possible by the means of attaining the object, according to the present invention.
- FIG. 1 Shows a first exemplary embodiment of a fire alarm which can be installed flush with the ceiling;
- FIG. 2 Shows a second exemplary embodiment of a fire alarm.
- FIG. 1 A first exemplary embodiment of the present invention is shown in FIG. 1 .
- a fire alarm 1 is shown in a cross section.
- Fire alarm 1 includes a flush-mounted installation outlet 1 . 4 for installation of fire alarm 1 in a recess 5 of ceiling 4 , into which a cable—which is not shown in the drawing—is inserted for connecting fire alarm 1 .
- Fire alarm 1 also includes a base 1 . 5 which is connected with the interior of flush-mounted outlet 1 . 4 and on which the electrical wires of the cable are attached to contact elements.
- Fire alarm 1 also includes a fire alarm insert 1 . 1 which is inserted in base 1 . 5 with a detachable connection device and is thereby automatically connected with the contact elements.
- Fire alarm 1 also includes a preferably transparent covering cap 3 and a replacable sheet 2 located between covering cap 3 and fire alarm insert 1 . 1 .
- flush-mounted outlet 1 . 4 and base 1 . 5 are preinstalled, independent of fire alarm insert 1 . 1 itself. At this point it does not matter at which point during installation when ceiling 4 is painted. When ceiling 4 is painted, it is usually necessary for fire alarm insert 1 . 1 to not be installed.
- Fire alarm insert 1 . 1 is typically installed in base 1 . 5 by technical personnel, who then checks it for proper functioning. Before inserting fire alarm insert 1 .
- a further exemplary embodiment of a fire alarm 1 is shown in a cross section in FIG. 2 .
- a flush-mounted installation outlet 1 . 4 is also provided here, it being secured in a recess 5 of ceiling 4 .
- a base 1 . 5 is located in flush-mounted installation outlet 1 . 4 .
- a fire alarm insert 1 . 1 is detachably connected with base 1 . 4 .
- fire alarm insert 1 . 1 . secured in base 1 . 4 does not overlap the edge of base 1 . 4 .
- an annular faceplate 3 . 1 is also provided, faceplate 3 . 1 enclosing covering cap 3 .
- This faceplate is also advantageously designed such that it is easily removed, so that a sheet 3 . 1 can also be inserted in this annular edge region.
- the color of ceiling 4 can not be matched with the color of sheets 2 , 2 . 1 in every case, since the number of sheets 2 , 2 . 1 is limited.
- additional optical effects can also come into play, however. The reason for this is that the optical characteristics of covering cap 3 and faceplate 3 . 1 also play a role in the observer's perception of color. Due to the curvature of covering cap 3 and/or faceplate 3 .
- covering cap 3 is preferably designed slightly convex in shape. This effect can be enhanced further by not designing the entire covering cap 3 and/or faceplate 3 . 1 to be transparent, but rather to provide it with a slight mat finish. In this case, fire alarm 1 looks like a slightly milky cover on the ceiling surface. Any other differences in color nuances that may still exist can no longer be distinguished.
- a replaceable neutral sheet 2 , 2 . 1 with a suitable surface structure, which can be painted on-site in the ceiling color and that, after drying, is inserted in fire alarm 1 . This also allows the color to be matched individually and exactly to the existing ceiling color.
